WebSymmetric Matrices and Quadratic Forms We have seen that orthogonal matrices have a particularly convenient property: their inverses are their transposes (and hence are substantially easier to compute than inverses in general). We have also used inverses in an important computational context - to diagonalize a matrix, when that is possible.
